The ProGuard Quietear Earplug is truly innovative earplug designed and patented offer variable noise reduction (VNR) technology, letting you hear what you need to hear (voices and other sounds in the voice frequency range) while protecting you from dangerous higher frequencies, and providing increased attenuation as the noise volume at the ear increases.

QuietEar earplugs have a built-in acoustic filter in the form of a precisely designed vent. As the volume of noise increases at the ear, QuietEar automatically provides increased attenuation, resulting in higher noise protection at higher noise levels. This means at lower noise levels, you can easily hear voices without having to remove your earplugs. In addition, QuietEar offers differential noise attenuation at high and low frequencies, which means sounds in the range of the human voice are always attenuated less than the higher, more dangerous, frequencies.

The vent also means QuietEar is more comfortable for extended wear, allowing your ears to breathe and reducing the "plugged-up" (occlusion effect) feeling common with many solid earplugs.

Made of durable and washable pre-moulded silicone, QuietEar plugs last for months or even years as long as they are cleaned with mild soap and water after each use.

Perfect ear plug for all the following applications:

- Motorcycling
- Industrial work areas where you need to have protection but still need to hear voices
- Shooting and hunting
- Military and police tactical applications
- Loud concerts
- SNR = 22dB
